Whether just for oil changes or general work on your cars, I'm guessing most people put on at least a different shirt than risk messing up their street clothes. How bad does it have to get, with rips, tears and stains before you get rid of it? Or go out in public wearing it? This Mercedes golf shirt is approaching the end with many holes and light oil stains, and I wont go anywhere wearing it. How bad does your repair wear have to get before tossing it?
